This article addresses short duration and repeated season long grazing trials which were initiated on the Dickinson Experiment Station Ranch Headquarters and Central Grasslands Research Station in 1981 and in 1982. Forage production has generally been greater on the SL treatment when compared to the SD treatment. Cows have maintained seasonal weight gains better on the SL treatment. Increased calf gains/acre on the SD treatment at both locations is a reflection of greater stocking rates on this grazing treatment.
